4409名学生心理健康状况及家庭环境与吸烟行为分析

目的:探讨中学生心理行为特征和心理健康状况及家庭心理环境与中学生吸烟行为的关系.方法:以苏州市4409名初中、高中、职业中学的学生为对象,采用SCL-90、家庭环境量表和自编问题进行问卷调查.结果:反叛性、冒险性强,倾向早熟、毅力差、顺从敏感性高是吸烟的危险因素,而情感调节性和认同敏感性与吸烟无关;吸烟组与对照组SCL-90在总分、阳性项目数、躯体化、强迫症状、人际关系敏感、抑郁、焦虑、敌对、恐怖、偏执、精神病性方面的评分均高于对照组,且有统计学意义(P＜0.01);吸烟组在FES-CV中的亲密度、情感表达、知识性、道德宗教观、组织性平均分明显低于对照组(P＜0.01),而在FES-CV的矛盾性的平均分则明显高于对照组(P＜0.01).结论:中学生行为的反叛性、冒险性、早熟性、毅力性和不良心理健康水平是中学生吸烟的危险因素;同时不良家庭关系也是中学生吸烟的危险因素,一个亲密、融洽的家庭环境可能会减少中学生吸烟,而一个矛盾的家庭则可能会增加中学生吸烟.     

Trajectories of risk behaviors and exiting homelessness among newly homeless adolescents

Using cluster analysis techniques, we identified two distinct clusters of newly homeless adolescents in Los Angeles (n = 261): those who are protected and doing relatively well while out of home with more protective than risk factors, and those who are risky with more risk than protective factors. The objective of this study was to examine the trajectories of human immunodeficiency virus (HIV) risk behaviors and exiting homelessness among protected newly homeless adolescents, compared to those who are classified as risky. HIV risk behavior included unprotected sex, having multiple sex partners and hard drug use. Logistic regression mixed-effects models were used to evaluate the trajectories of HIV risk behaviors and exiting homelessness over time. The adolescents in the protected group reported significantly less unprotected sex ( p = 0.0156), being abstinent or monogamous ( p < 0.0001) and less hard drug use ( p < 0.0001) compared to the adolescents in the risky group. In addition, the protected group reported more “exiting homelessness”, compared to the risky group ( p = 0.0007). However, the differences in the level of unprotected sex between the protected and risky groups decreased over time. Our findings confirm the notion that newly homeless adolescents are indeed heterogeneous. Given that the risk behavior profiles of protected group merges to the risky group over time, our findings underscore the need to mount tailored interventions to be designed for the protected group early in the process.
